US 2011/0085604 A1 · IMAGE PROCESSING DEVICE, SYSTEM AND METHOD

Abstract

According to one embodiment, an image processing device includes an image decoder, an encoding difficulty calculator, an encoding difficulty modifier, a coding volume controller, an image encoder. The image decoder is configured to decode a compression coded input video signal and configured to calculate an image characteristic value of the decoded signal. The encoding difficulty calculator is configured to calculate a first encoding difficulty indicative of a compression-coding difficulty of the decoded signal based on the image characteristic value. The encoding difficulty modifier is configured to generate a second encoding difficulty based on the first encoding difficulty and an image characteristic information set from outside for re-compression-coding the input video signal with a predetermined coding volume. The coding volume controller is configured to set a coding volume to be assigned based on the second encoding difficulty. The image encoder is configured to generate an output video signal by re-compression-coding the decoded signal with the assigned coding volume.
